References the flow-layout rule set in the EVOLV superproject
(.claude/rules/node-red-flow-layout.md) so Claude Code sessions working
in this repo know the S88 level, colour, and placement lane for this node.

- Fix flowmovement unit mismatch: MGC computed flow in canonical (m³/s)
but rotatingMachine expects output units (m³/h). All flowmovement calls
now convert via _canonicalToOutputFlow(). Without this fix, every pump
stayed at minimum flow regardless of demand.
- Fix absolute scaling: demandQout vs demandQ comparison bug, reorder
conditions so <= 0 is checked first, add else branch for valid demand.
- Fix empty Qd <= 0 block: now calls turnOffAllMachines().
- Add empty-machines guards on optimalControl and equalizePressure.
- Add null fallback (|| 0) on pressure measurement reads.
- Fix division-by-zero in calcRelativeDistanceFromPeak.
- Fix missing flowmovement after startup in equalFlowControl.
- Add marginal-cost refinement loop in BEP-Gravitation: after slope-based
redistribution, iteratively shifts flow from highest actual dP/dQ to
lowest using real power evaluations. Closes gap to brute-force optimum
from 2.1% to <0.1% without affecting combination selection stability.
- Add NCog distribution comparison tests and brute-force power table test.
